A look into Transparency International's latest report on corruption around the world.

Its annual Corruption Perception Index reveals some alarming trends. It shows public service corruption is still a huge problem for two-thirds of the world's economies.

The report uses a scale of zero to 100 to rank countries: zero is highly corrupt and 100 is very clean. Syria, South Sudan and Somalia rank lowest with scores of 14, 12 and 9 respectively. New Zealand comes out on top but with a score of 89.

CORRUPTION PERCEPTIONS INDEX 2017

This year’s Corruption Perceptions Index highlights that the majority of countries are making little or no progress in ending corruption, while further analysis shows journalists and activists in corrupt countries risking their lives every day in an effort to speak out.

The index, which ranks 180 countries and territories by their perceived levels of public sector corruption according to experts and businesspeople, uses a scale of 0 to 100, where 0 is highly corrupt and 100 is very clean. This year, the index found that more than two-thirds of countries score below 50, with an average score of 43. Unfortunately, compared to recent years, this poor performance is nothing new.
